MUTOGRAP-I.

T o all whom it may concern:

Be it known that I, FRANK C. NiiwaLL, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Mutographs, oi" whichthe following is a specification.

The invention relates to display apparatus oi' the general type shown inmy Patent No. 891,949 of June 30th, 1908, wherein a mosaic plate isutilized to impress symbols upon a moving' band. The invention has forsome of its principal objects; the provision of a machine h vingimproved and simplified selector operating and controlling means, andone which may be operated by a keyboard removed at any desired distancefrom the symbol forming mechanism g theprovision at the keyboard ofmeans for registering in replication the sign produced on the band; theprovision of a mosaic plate having animproved system of division lineswhereby the danger of improperly actuating the stipples of the stipplemember with which the mosaic is ordinarily intended to be used, isavoided; and in general the provision of a machine wherein the partsoperate with greater rapidity and positiveness than has been the case inmutograph machines as heretofore constructed. One embodiment of theinvention is illustrated in the accompanying drawings, wherein :n

Stated brieliy, the device comprises in its preferred form an endlessbelt or band mechanism in which the band is adapted to be carried past areciproca-ble symbol or mosaic plate, whereby a series of characters areproduced on the band. The mosaic plate is composed of relatively movablesections with operating means therefor, whereby all the various symbolsmay be produced by a different arrangement of the sections compris-- ingthe plate. The variations in symbols are produced by means of a rotaryadjustjab'le member or selector as it will be called,

which selector in its various positions adapted t-o actuate differentsets of sections in the mosaic plate to produce the various symbols. Theselector is stopped in any one of its various positions by means ofelectromagnetic means, Which means are controlled from a keyboardprovided with sets of contacts operated by the keys. The frame-Workcarrying the selector and mosaic plate is oscillated back and forth inthe direction of travel of the band in order that the band andimpressing symbols may have the same motion when they come together, andthe frame carrying the mosaic plate is also given a reciprocatorymovement for producing its symbol upon the band. The band is of the typeshown in my patent heretofore referred to, and is so constructed as toshow on its face the symbol produced in a color contrasting to that ofthe body of the band. The band is made to pass the mosaic plate by'means of a rotating turret constituting a part of the mechanism overwhich the band passes. The band travels to a position Where it isexposed to View, and before its return to the machine the symbolsproduced are obliterated, and the band is ready for a new set ef symbolswhen it again reaches the impressing mechanism.

As shown in assembled form in Figures 1, 2, 3, t, 5, 6, 8, 9 and 15, theprincipal parts of the machine are the endless display belt A (Figures1, 2 and 15), the supporting and operating turret B at one end thereof,which act-s as a drive sprocket, the mosaic plate C made up of aplurality of movable sections from which all the symbols are to beformed in relief, and adapted to be moved against a belt, the selector DWhich controls the production of the various symbols upon the mosaic,which selector is `controlled and stopped in its various positions bymeans of electromagnetic means, the keyboard E (Figures G, 8 and 9)which controls the electromagnetic means for stopping the selector' inany desired position, the printing mechanism F which registers thesymbols printed by the operation of the keys of the keyboarc and showsat the keyboard, a replication of the sign being produced upon thedisplay band A, the carrier frame G which carries the mosaic plate Whichis moved back and forth to impress the symbol upon the display band, thesupporting frame H for the carrier frame and selector which is adaptedto be given an oscillatory motion in the direction of travel of the bandWhen it engages the band to give its impression, the main supportingframe I for the device, upon which all the other mechanism is supported,and the device J for retracting the stipples.

Referrings first to Figures 1, 2 and15,\vhch illustrate the means foroperating the endless band A, it will be seen that one of the sprocketsfor such band, is the turret B from Which the band is driven, and thatat the other end the band passes around an idler sprocket 1at ofcorresponding shape. The turret B consists of a spider frame having inthe present instance 12 arms 2, each provided with a depending rod 3adapted to engage and support the ends of the links constituting theendless band, (Figure 2). The turret is pivotally supported at itscenter upon the shaft et, and is driven from the main drive shaft 5 ofthe machine by means of the gear 6 secured to the turret and meshingWith the pinion 7 on the upper end of the shaft 5. This shaft 5 isprovided at its lower `end -With a Worm gear la which is driven from acontinuously operating motor (not shown). The construction of theendless band A which engages the turret B will be described in detailhereinafter.

The mosaic plate employed for impressing the symbols upon the stippleband is of the general type illustrated in my patent referred to, and isshown in Figures 1, 17, 1S and 19. From these views it Will be seen thatthe face of the plate is divided into a plurality of sectionsreciprocably mounted in a frame 8, and each section is supported by apin 9, provided with a spring 10 normally tending to force the sectionto its rearmost position. By allowing certain of these pins to beoperated by the springs to force them back, the other sections may beallowed to stand out in relief, forming the desired symbols. In Figure 1a part of the sections are shown as held in a di'erent plane from theremainder of the sections thereby forming a symbol in relief upon theface of the plate. As illustrated in Figure 17, the plate is dividedinto about sixty sections by which all of the letters and numerals up to9 may be produced in block style. The manner in which the variouscombinations of sections may be arranged to secure the various symbols,may be determined by an inspection of Figure 17, without a detaildescription as to which blocks must be actuated in order to produce allthe various symbols. The mosaic plate shown in Figure 17 differsprincipally from that of my patent application referred to, in that theinclined dividing lines between the various sections are stepped, thepurpose being to remove as far as possible the inclined dividing linefrom the rear ends of the stipples to be engaged, and so insure theproper engagement of the sections with the stipples, even though theplates be moved laterally slightly by the vibration of the machine. Thisis clearly illustrated diagrammatically in the upper left hand corner ofthe figure wherein the rear ends of the stipples are represented by thesmall circles, and the dotted line -m indicates the line of divisionbetween the sections as constructed in the old form of device. It willbe seen that the distance from the dividing line to the rear ends of thenearest stipples is increased by the stepped arrangement.

In order that the mosaic plate may impress its symbol upon the band A,two motions must necessarily be imparted to it, first, a movement ofreciprocation to bring the plate against the band, and second, anoscillatory movement in order that the plate may move in the directionof travel of the band, whereby the travel of the lband need not beinterrupted during the impressing. To secure these two motions, thecarrier plate or frame Gr upon which the mosaic plate is seated, ismounted for sliding reciprocatory movement, and this reciprocatory frameGr is in turn mounted upon an oscillatory frame H mounted upon thevertical pin 11. Referring first to the construction of the slide frameG and the means for operating it as shown in Figures 1, 3, 4, 5, 26 and27, it will be seen that the frame G has at its base (Figure 3) twolaterally projecting flanges 12 tting between a pair of twopart guidemembers 13, whereby the frame is guided transversely upon the top of theoscillatory frame H. The frame G is reciprocated by means o-f the crankdisk 14 at the rear of the machine, which crank disk is connected withthe frame G by means of the connecting rod 15. The crank disk is mountedupon the pillar 16 and has integral with its lower portion a pinion 17,which pinion 17 engages a segmental gear 18 mounted upon the shaft 5.The number of teeth upon the pinion 17 is the same as upon the segmentalgear 18, so that one complete revolution of the shaft carrying thesegmental gear 18 gives the crank disk 14 a complete revolution, andadvances and retracts the sliding frame G carrying the mosaic plate. Theparts are so arranged that this movement of advance and retraction takesplace during that half of the oscillation of the main frame H in whichthe mosaic plate is following the movement of the band, and impressingits symbol thereon, which movement may be termed the forward movement ofthe oscillatory frame H. During the other half of the oscillation of theframe H, or return movement, during which the mosaic is returning to itsstarting point, there is no reciprocatory movement of the frame G as thesegmental gear 18 is out of mesh with the pinion 17, and it is duringthis return movement that the setting of the selector hereinafter to bedescribed, takes place. In order that the crank disk 14 be held securelyin position when the segmental gear 18 is out of mesh with the gear 17,the recess 19 (Fig. 26) is provided in the periphery of the crank disk,and this recess 19 is engaged by a segmental disk 20 mounted above thesegmental gear 18 and integral with the hub of such segmental gear. Itwill be seen that as the gears 18 and 17 disengage, the segmental disk20 engages the recess 19, and the disk 14 is positively prevented fromany movement until the parts 2O and 19 are disengaged. In order that theteeth of the two gears may properly mesh when they come together, thepin 21 is provided on the gear 18 in a position to take against themember 22 secured to the underside of the gear 17. This arrangementtakes the strain oft' the end teeth of the segmental gear and insures anoiseless engagement. The oscillatory frame H which carries the slidingframe G just described, is pivoted upon the vertical pin 11, which issecured in the main frame I, and the antifriction bearing shown (Figure3) is provided. An oscillation of this frame about its pivot pin 11 issecured by means of the camming arrangement shown in Figures 1, 5 and28. The heart-shaped cam 23 is mounted to rotate with the drive lshaft5, and this cam 23 drives the slide 24, which in
